This book is helpful, but shouldn't be the first book someone picks up about Joyce. He focuses largely on colonial and Freudian looks at Joyce's writing, much of which is spot-on, but at times feels way over the top.
Very useful. I often question the inclusion or exclusion of some things, but overall a solid guide. One qualm - why explain what chapter in the Odyssey each chapter of Ulysses corresponds with but only sometimes pose hypotheses on the connection between to the two?
